saltationism
Very LowAcademic / Technical
Definition
Meaning
The biological theory that evolution occurs primarily through sudden, major changes (saltations) rather than gradual, incremental steps.
In a broader sense, any theory or belief in sudden, discontinuous leaps or jumps in development, whether in biology, geology, or other fields, as opposed to gradualism.
Linguistics
Semantic Notes
The term is primarily used in evolutionary biology and paleontology. It is often contrasted with 'gradualism' or 'phyletic gradualism'. It is associated with historical debates in evolutionary theory and is not a mainstream contemporary view.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Spelling follows standard national conventions for the suffix '-ism'.
Connotations
Equally technical and niche in both varieties. May carry a slightly pejorative connotation of being a non-standard or outdated theory in mainstream scientific discourse.
Frequency
Extremely rare in both varieties, confined almost exclusively to academic texts on the history and philosophy of evolutionary biology.

Examples
By Part of Speech
verb
British English
- The theory was said to saltationise evolutionary change.
- He argued that species could saltate.
American English
- The theory saltationized the concept of speciation.
- Fossil evidence suggested the lineage had saltated.
adverb
British English
- The species evolved saltationistically, according to the hypothesis.
American English
- Change was thought to occur saltationistically rather than gradually.
adjective
British English
- His saltationist views were controversial.
- A saltationist interpretation of the fossil record.
American English
- The saltationist model proposed rapid morphological jumps.
- She held a saltationist position in the debate.
Examples
By CEFR Level
- Saltationism is a very difficult science word.
- Saltationism is a theory about fast evolution.
- In biology, saltationism argues that evolution happens in big jumps, not small steps.
- The paleontologist's saltationist interpretation of the fossil gaps challenged the prevailing gradualist paradigm, reigniting debates about evolutionary tempo.
Learning
Memory Aids
Mnemonic
Think of 'SALT' + 'ATION' + 'ISM'. Imagine evolution taking a big leap, like adding a large spoonful of SALT all at once, not grain by grain. The '-ISM' makes it a theory or belief.
Conceptual Metaphor
EVOLUTION IS A JOURNEY performed in LEAPS AND BOUNDS rather than small steps.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'скачкообразность' in a general sense; it is a specific scientific term. The direct equivalent is 'сальтационизм'. Do not confuse with 'скачок' in dialectical materialism.
Common Mistakes
- Misspelling as 'saltaionism' or 'saltationnism'.
- Confusing it with the more modern and nuanced theory of 'punctuated equilibrium'.
- Using it as a general synonym for any sudden change outside of evolutionary theory.

FAQ
Frequently Asked Questions
No, they are related but distinct. Punctuated equilibrium (Eldredge & Gould) describes long periods of stasis 'punctuated' by rapid speciation events, but still within a population genetics framework. Saltationism historically implied sudden, major mutations creating new forms or species in a single generation.
No, it is not a mainstream theory in modern evolutionary biology. The modern synthesis and subsequent developments emphasise gradual change acted on by natural selection, though mechanisms like polyploidy (instant speciation in plants) are accepted saltational events.
The primary opposite is gradualism or phyletic gradualism, which posits that evolutionary change occurs slowly and continuously through the accumulation of small variations.
Rarely, but it can be used metaphorically in fields like geology (for sudden geological changes) or sociology/theory of change to describe any model proposing discontinuous leaps rather than incremental progress.
